ABSTRACT Objectives: The objective of this study is to determine the prevalence of Chlamydia trachomatis and risk factors for positive repeat tests in a high-risk population presenting for early prenatal care. Methods: We completed a retrospective cohort study of 2,484 women who initiated prenatal care prior to 20 weeks gestation, delivered, and received testing for cervical C. trachomatis at Grady Memorial Hospital or a Grady-affiliated clinic between July 1, 1993 and Deeember 31, 1994. We calculated adjusted odds ratios (OR) for selected risk factors for a positive initial test and for a positive subsequent test after an initial negative test. Results: The prevalence of C. trachomatis was 14.8%. At initial testing, 10.4% of the women were positive. If the initial test was negative, 5.7% had a positive subsequent test; but if the initial test was positive, 32.0% had a positive subsequent test (P
